Your English is good enough, I think I understand what you mean. Dialogue progression is the main issue here, I think. Progression in general is a bit wonky, rushed and almost non-existent in this game. The game might be "finished" as in all the main scenes are added in but regular every-day dialogue outside of sex still needs to be updated. For example the breakfast scene with Katherine and Adrianna. They still act secretive about the whole sex thing even after the threesome scenes. The developer mentioned that now that all the main scenes are finished they can start working on better progression without fear of breaking something else in the game. Hopefully they follow through on that in future updates.
